Tree Indiana Native Carya ovata [Shagbark Hickory] The bark of Carya ovata gives the tree its common name and is characteristically rough and shaggy on mature trees, growing in long flat plates, making especially good winter interest. The wood of this tree is especially hard, making it useful for a variety of products. This tree develops a large taproot, making it difficult to transplant.
Tree Indiana Native Carya tomentosa [Mockernut Hickory] This tree is found on ridges, dry hills, and slopes but grows best in moist, well-drained soil. The fall color is deep golden yellow to golden brown and persists. Fruit is round to elliptical with a thick husk splitting at the base and contains an edible seed.
Tree Indiana Native Catalpa speciosa [Northern Catalpa] Coarse winter trunks and branches are bold and striking; picturesque. Best for difficult areas. Wood is rot resistant, but is somewhat brittle so branches can fall in wind and ice storms. Too coarse of texture for most urban landscapes. Short-lived to about 50 years.
Tree Indiana Native Celtis laevigata [Sugar Hackberry] The Sugar Hackberry is very similar to the Common Hackberry (Celtis occidentalis) and is especially useful in large-scale situations with dry soils and heavy winds. This species gained its common name from the juicy, sweet berries it produces. Subject to a leaf nipple gall (caused by psyllid insect Pachypsylla dismamma, one of many jumping plant lice). However, the Sugar Hackberry is more resistant to witches'-broom disease (caused by Eriophyid mite) than the Common Hackberry. Especially…
Tree Indiana Native Celtis occidentalis [Common Hackberry] As well adapted to Midwestern conditions as American Elm, and a reasonably good substitute in form as well. Especially useful in large-scale situations with dry soils and heavy winds. Subject to a leaf nipple gall (caused by psyllid insect Pachypsylla dismamma, one of many jumping plant lice) and witches'-broom disease (caused by Eriophyid mite), both minor in most situations in the Midwest. Especially coarse texture limits use in designed landscapes.
Shrub Indiana Native Cephalanthus occidentalis [Common Buttonbush] Buttonbush is an Indiana native and a wet-soil tolerant shrub found near marshes, wetlands, and river banks. This is a great choice for those wet areas in the landscape or a featured shrub in your rain garden. The flowers of this shrub are globe-like in shape and bloom from June through August, attracting wildlife such as butterflies. The leaves of the Buttonbush emerge late in the Spring and might look dead until mid-May. Though this…
Tree Indiana Native Cercis canadensis [Eastern Redbud] A fine small tree that grows wild in many parts of Indiana. Relatively trouble-free and drought-resistant. Requires some protection from the sun in hotter climates, however flowering decreases with deep shade. Canker, leaf spot, and verticillium wilt can be problematic for older trees, or trees weakened by other environmental stresses. Due to genetic variability, be sure of seed source. Long tap root means that older plants transplant poorly.
Tree Indiana Native Cladrastis kentukea [American Yellowwood] A highly ornamental native tree, even though the pendulous clusters of flowers do not appear in great numbers every year. Well-adapted to Midwest conditions. Develops a tap root. Does not flower fully each year; part of a tree may flower one year, part the next, but the effect is striking even when only certain branches bear flowers. Bees are attracted to the flowers. Flowers appear only after many years from seed. Avoid pruning in spring…
Shrub Indiana Native Clethra alnifolia [Summersweet Clethra] Spreads by underground stems to make large clumps, but can be restrained when necessary. Can be badly infested with mites, especially on dry soils. Can suffer in full sun and/or dry soils, but can bloom well in shade.
Tree Indiana Native Cornus alternifolia [Pagoda Dogwood] Broad-spreading, low branched, forming stratified tiers, very interesting branching habit. Leaf spot and twig blight/canker can be problem for older trees.
